How much do you think the "cross domain duplicate content" effects things, as I have heard straight from Matt that "Google expects some amount of duplicate content" and that a site should have added value in addition to the dup content (I assume such as a way to interect with it in some manner, or other content that related to the content in a different manner)

True? Crap?

As an aside, I reached PR 2 in a couple weeks with pure dup content drips ..
